For me, professional studios are Companies from, I don't know, 20 to 50 rendernodes. Make >3 minutes FullHD animation or heavy production like catalogue >4K with 30 or 40 shots. Not a single man in a room with 2 PC to make a nice rendering for Evermotion gallery ;-) If I have a robust DR I can do strong job. Without no, I can't. I can simulate SSS, or I do fake IES. I cannot simulate DR. But this is my point of with. Anyway, today I read the entire (ALL) forum. I like Corona, very much...

People in companies with 20-50 rendernodes are usually smart enough to use backburner or any other network rendering manager to distribute rendering of individual animation frames across all the nodes they have, instead of using less efficient way of rendering each frame on a single computer and transferring pieces of scene back and forth between all the nodes contributing to DR.

Only scenario where DR really shines is rendering of huge resolution complex still images.

I didn't test it with corona (yet) but, for example, deadline is able to render tiles. So you could split up (automatically) a highres rendering to 5x5 tiles and send it to the farm which should be pretty much the same speed than doing it via DR.Sure, it is a bit more comfy to do it with DR but at the end its still possible to do it this way - and that's why DR is not that important for me atm. I would way more profit from things like light include lists or ies or matteshadow (which can be the killer argument when choosing the right renderer for a production)

"Every professional studios (ad clients :' ( ) want speed before SSS, IES etc..." Well... How about professional studios doing full featured CGI shots and trailers for games etc, like let's say blur...?

From a personal point of view, DR is of most use when I need to turn out a large image fast and in emergencies, otherwise I'll just submit via bb and wait. Having said that there seem to be more and more 'emergencies' from my clients atm ;-)
